American academy of pediatrics states taht breastfeeding should be avoided for children with congenital heart disease because it requires less energy to suck from a bottle than the breast.

Breastfeeding is actually encouraged for infants with congenital heart disease because it provides easier digestibility, better nutrition, and helps with bonding. It also offers optimal growth and development in most cases. Bottle-feeding, on the other hand, might require more energy and can be more difficult for infants with CHD, which is why breastfeeding is often preferred when possible.
